Does anyone know how to set up a material to use Texture Data like with the Fortnite assets ?
Like this :
Yes,
I’ll hafta do this from memory…currently building HLODs
Right click on Content Browser and add, I think its in Miscellaneous > Data Asset
then choose Building texture data… or something similar
It will create a new object in one of your project folders in the Content Browser.
Double click to open it, then you’ll be able to drop your material in the Material Override slot.
Save and Close, then you can drag the new texture data asset into the Primary and Secondary slots of the prop.
Sometimes the material won’t show on the prop, so I usually add the material that was used in the override material slot, on the props static mesh component as well.
Most props have an allow Custom material setting which needs to be ticked, either in the props settings or its static mesh component settings.
There is also the breaking effect, when the prop is damaged. This effect is a material property and if you want this you have to use an instance of the MI Fort Parent Base material (or a similar sounding name, which I can’t look up yet…but you’ll find it in the Fortnite/Materials folder somewhere)
and add your material stuff to that. It works a bit differently to the materials editor, using settings instead of the node graph.

Yes, thats it, like that
But I have been using the Override Material Slot below the Diffuse, Normal and Specular slots, it lets me use a standard material, where I have been using the modified fortnite base material for the breaking effect.
I’m not too good with creating D, N or S, its easy to make a simple material from a texture and drop it into the override slot.
Thanks for showing that vid, it expanded my awareness a bit because I’ve been ignoring the DNS slots 
Ok but I already know this.
I’m not asking how to make a “data asset used by the material” but how to make a “material using data assets”.
Because when I import a custom mesh with a custom material I can’t use this feature except for first slot. Changing the data asset in the three last ones have no effect on the prop using the imported mesh.

Ah hah.
That I don’t know,
I remember a post way back, someone was asking for these to be made available for custom stuff.
Hopefully someone can shed some light…
maybe need a feedback & requests with some voting ???
